thanks very much for the response, the link for your thread and the video.. (and thanks Glenn too, hi
It's all incredibly interesting.. I think what Ive realized that right now in the situation I am in (wanting to get some heating going pretty quickly for the winter without causing too much trouble/keeping it simple.. we are already sleeping in there sometimes and its getting pretty cold) that I might go for a regular wood burner as a short term solution and then try out a rocket heater at a more suitable point in a more suitable building... maybe trying an outdoor one first
The cabin is very small, so I also feel it might be some engineering job to make sure it doesn't overheat, (i have read they can burn very hot) or just causes more harm than good..
its probably sensible to wait till ive got a bigger space/do some outdoor trials.. and then plan it into the building from the outset..
now it feels best to take my time on this one, especially as i have various other things on the go..
Thanks for the help.. it seems another issue in itself to find a suitable small wood over to buy for such a small cabin, outside the USA where some manufacturers make super mini ones (ie Fatsco Tiny Tot) at a good price.. the smallest one i can find here is 4kw.. which is suitable for up to 40m2, apparently.. and I have a mere 9m2.. id love to find a super mini regular wood stove that I can actually get hold of, but it doesnt seem possible, unless anyone has any recommendations on that.. ?? Im in Germany..
